A large open space in or in front of a building where people can gather, particularly one joining various paths, as in a rail station or airport terminal, or providing access to and linking the platforms in a railway terminus.

In east London in October 2013, during a game between West Ham and Manchester City, a small group of home Muslim fans - with no prayer room available - tried to offer their Maghrib (sunset) prayer on a concourse under the main stand at the club's former home Upton Park.

About three years ago, Mr. Gulliver growing weary of the concourse of curious people coming to him at his house in Redriff, made a small purchase of land, with a convenient house, near Newark, in Nottinghamshire, his native country; where he now lives retired, yet in good esteem among his neighbours.

Amidst the concourse were to be seen the noble ladies of Milan, in gay, fantastic cars, shining in silk brocade.

In sense "open space", particularly used of indoor spaces, by contrast with plaza, place, square, etc. However, may be used for outdoor spaces as well, primarily high-traffic areas in front of a building.
